One possible plotline could be that it's set after the war. Harry and Fleur find solace in each other's company. They might be sitting by the fireplace in the Burrow, and as they cuddle, they share stories of their past traumas. Fleur could talk about how difficult it was for her being part - Veela during the war, with people being both attracted and distrustful of her. Harry, in turn, would open up about his experiences with Voldemort. Their cuddling becomes a source of comfort and a sign of a new beginning for both of them.
Perhaps in an alternate universe where the Triwizard Tournament had a different outcome. Harry and Fleur end up getting closer during the tournament instead of the events that led to Cedric's death. They start to develop feelings for each other, and the cuddling is a result of their growing affection. Fleur might teach Harry some French, and as they cuddle, they whisper sweet nothings in both English and French to each other, creating a very romantic and cozy scenario.
It could be a story where they are on a mission together. They are in a cold and dangerous place, and to keep warm and safe, they cuddle. At first, it's just a practical measure, but then they realize their underlying feelings. Harry is amazed by Fleur's bravery and beauty, and Fleur is drawn to Harry's selfless and heroic nature. As they cuddle, they make plans on how to complete their mission and also about their future together if they survive.
A plot could involve Fleur's sister having a special ability that she has to keep hidden. Harry discovers this secret accidentally. For example, she might be able to communicate with magical creatures in a way no one else can. Together, they could use this ability to help Hagrid with some of his more dangerous and unruly creatures. Or, she could be a target of the Death Eaters because of her family's connection to the Beauxbatons Academy. Harry then has to protect her, leading to a series of action - packed scenes around Hogwarts and the wizarding world.
A really interesting plotline could be set in a post - war scenario. Fleur, who has always had a crush on Harry, decides to actively pursue him. She starts by sending him anonymous gifts, which Harry is very curious about. When he finally figures out it's Fleur, they start to have conversations about the war, their losses, and slowly their relationship blossoms into something more than just a crush.
In one plotline, Fleur could be the target of a curse that slowly drains her magic. Harry, as her bodyguard, has to find a way to break the curse while keeping her safe from those who might want to take advantage of her weakened state. This could involve seeking out ancient spells and potions, and they might have to journey to dangerous and mysterious places. As they do so, their relationship could evolve from Harry simply being a protector to someone Fleur deeply trusts and relies on, and there could be hints of a romantic connection developing between them.
One interesting plotline could be the cultural clashes between the two families during the wedding preparations. For example, Fleur's French heritage might bring in different wedding traditions that Harry's friends and family find strange or exciting. Another could be the role of magic in the wedding decor. Maybe there are enchanted flowers that change colors or float in the air. Also, the reactions of the guests, like Hermione's thoughts on the whole event, could be a great part of the story.
Well, a common plotline is the development of relationships within the harem. For example, Harry might initially be a bit hesitant about the whole harem concept, but as he gets to know Fleur and the other potential members, he starts to embrace it. There could also be a plot where they are all on a quest to discover some ancient magic, and during this journey, their bonds in the harem become deeper and more complex.
One interesting plotline could be how Harry and Fleur adjust to their betrothal. Maybe they start off as strangers and gradually learn about each other's likes and dislikes. Another could be the reactions of their friends, like Ron might be jealous at first or Hermione might be a bit skeptical but then come around.
It could be that they leave to attend a special magical training that is only available in a very secluded place. They might have received an invitation from a very powerful and reclusive wizard. This training could enhance their magical abilities in ways that Hogwarts or Beauxbatons couldn't. They see this as an opportunity to become stronger and more self - reliant, so they leave together, excited for the new challenges and knowledge that awaits them.
One possible plot could be that Fleur has been influenced by some dark magic or a powerful enemy. Maybe she's being blackmailed to kidnap Harry. She might take him to a hidden location, perhaps an old, abandoned castle. Then, the story could revolve around Harry trying to figure out why Fleur did this and how to escape while also dealing with Fleur's internal struggle about what she's done.
I'm not sure specifically as there could be many different interpretations of such a fanfiction. It might be about Harry having some sort of unique relationship with Fleur in a fictional scenario created by the fanfiction writer.
In some fanfictions, Fleur and Harry start off as friends. Fleur, being older and more worldly, gives Harry advice on how to handle the media attention he gets as the Boy Who Lived. As time passes, they realize they have deeper feelings for each other. They might go on secret adventures around the wizarding world, away from the prying eyes of the public, and that's where their love story really begins.
